  • a position of the dividing wall 44 of the dividing member 23 is set closer to a left side (the side of the second space S2) compared to the toner container 6 for a low speed machine (the printer 1 with a low printing speed). Consequently, it is possible to increase a filling amount of the toner to the toner container 6 for the high speed machine compared to the filling amount of the toner to the toner container 6 of the low speed machine.
  • a user can select the toner container 6 having a volume satisfying a desired printing number. For example, a user who frequently uses a toner (who frequently prints sheets) may select the toner container 6 having a larger volume even though the toner container 6 is expensive. On the other hand, a user who does not frequently use a toner (who does not frequently print sheets) may select a low cost toner container 6 even though the toner container 6 has a smaller volume.
  • the filling port 32 is arranged, and the dividing member 23 includes the dividing wall 44 which divides the internal space of the case main body 22 into the first space S1 and the second space S2 and the communication pipe 45 which is installed between the left wall part 22L of the case main body 22 and the dividing wall 44, and communicates the filling port 32 with the first space S1.

  • the toner container 6 includes the blocking member 56 which is inserted in the communication pipe 45, and this blocking member 56 blocks the communication of the filling port 32 with the first space S1.
  • the toner container 6 includes the conveying screw 24 and the agitating paddle 25 which are rotatably housed in the first space S1, and, at the right face (the face at the side of the first space S1) of the dividing wall 44 of the dividing member 23, the first bearing part 52 which rotatably supports the left end part of the screw shaft 67 of the conveying screw 24 and the second bearing part 53 which rotatably supports the left end part of the frame body 71 of the agitating paddle 25 are arranged.
  • the dividing wall 44 which divides the first space S1 and the second space S2 as a bearing of the conveying screw 24 and the agitating paddle 25.
  • the dividing member 23 includes the packing 47 which is arranged along the outer edge of the right face (the face at the side of the first space S1) of the dividing wall 44.
  • the dividing wall 44 of the dividing member 23 divides the internal space of the case main body 22 in the left and right direction (the longitudinal direction of the case main body 22).
  • the discharging port 42 is arranged (at a part corresponding to the second space S2, the discharging port 42 is not arranged). Consequently, it is possible to discharge the toner from the first space S1, and prevent the toner from being discharged from the second space S2.
  • the filling amount of the toner to the case main body 22 is varied according to the specification (printing speed) of the printer 1 has been described. Meanwhile, in other different embodiments, according to a destination of the printer 1 or a color of a toner filled to the case main body 22, the filling amount of the toner to the case main body 22 may be varied.
